Blonde hair is a hair color that ranges from pale yellow to deep gold. It is caused by a lower concentration of the pigment melanin in the hair follicles. This hair color is most commonly found in people of Northern European descent, but it can also occur in other populations due to genetic variations. There are different shades of blonde hair, including platinum blonde, strawberry blonde, and dirty blonde. The appearance of blonde hair can change with age, often darkening over time. Additionally, blonde hair can be enhanced or altered using hair dyes and treatments in the beauty industry.
